CVSS: 10.0EPSS: 8%CPEs: 105EXPL: 2CVE-2008-1948 – GNUTLS-SA-2008-1-1 GnuTLS buffer overflow
https://notcve.org/view.php?id=CVE-2008-1948
The _gnutls_server_name_recv_params function in lib/ext_server_name.c in libgnutls in gnutls-serv in GnuTLS before 2.2.4 does not properly calculate the number of Server Names in a TLS 1.0 Client Hello message during extension handling, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a zero value for the length of Server Names, which leads to a buffer overflow in session resumption data in the pack_security_parameters function, aka GNUTLS-SA-2008-1-1. La función _gnutls_server_name_recv_params de lib/ext_server_name.c en libgnutls de gnutls-serv en GnuTLS versiones anteriores a la 2.2.4, no calcula correctamente el número de Nombre de Servidor en un mensaje Hello TLS 1.0 durante la gestión de extensiones, lo cual permite a atacantes remotos provocar una denegación de servicio (caída) o posiblemente ejecutar código arbitrariamente a través de un valor cero para la longitud de los Nombres de Servidores, lo que conlleva un desbordamiento de búfer en una sesión de reanudación de datos en la función pack_security_parameters, también conocida como GNUTLS-SA-2008-1-1. • http://git.savannah.gnu.org/gitweb/?p=gnutls.git%3Ba=commitdiff%3Bh=bc8102405fda11ea00ca3b42acc4f4bce9d6e97b http://lists.gnu.org/archive/html/gnutls-devel/2008-05/msg00051.html http://lists.gnu.org/archive/html/gnutls-devel/2008-05/msg00055.html http://lists.gnu.org/archive/html/gnutls-devel/2008-05/msg00060.html http://lists.opensuse.org/opensuse-security-announce/2008-09/msg00003.html http://secunia.com/advisories/30287 http://secunia.com/advisories/30302 http://secunia.com/advisories/3 • CWE-189: Numeric Errors •

https://notcve.org/view.php?id=CVE-2006-4790
verify.c in GnuTLS before 1.4.4, when using an RSA key with exponent 3, does not properly handle excess data in the digestAlgorithm.parameters field when generating a hash, which allows remote attackers to forge a PKCS #1 v1.5 signature that is signed by that RSA key and prevents GnuTLS from correctly verifying X.509 and other certificates that use PKCS, a variant of CVE-2006-4339. verify.c en GnuTLS anterior a 1.4.4, cuando usamos una llave RSA con exponente 3, no maneja correctamente el exceso de datos en el campo digestAlgorithm.parameters al generar un hash, el cual permite a un atacante remoto falsificar una firma PKCS #1 v1.5 que es firmada por esa llave RSA y evita que GnuTLS verifique correctamente X.509 y otros certificados que utilicen PKCS, es una variante de CVE-2006-4339. • http://lists.gnupg.org/pipermail/gnutls-dev/2006-September/001205.html http://lists.gnupg.org/pipermail/gnutls-dev/2006-September/001212.html http://secunia.com/advisories/21937 http://secunia.com/advisories/21942 http://secunia.com/advisories/21973 http://secunia.com/advisories/22049 http://secunia.com/advisories/22080 http://secunia.com/advisories/22084 http://secunia.com/advisories/22097 http://secunia.com/advisories/22226 http://secunia.com/advisories/22992 http://secunia&# •
